My budget is 3000/- for both keyboard and mouse (keyboard+mouse = 3000).

Main needs / usage of the keyboard and mouse is gonna be Gaming + Multimedia + Office werk.

Waiting for the recommendations. Kindly send approx rates along with the recommended model numbers.

I need to work on this 2day itself as its urgent. If nothing can be done then i'll have to go for genius.

To sum up, Genius Ergo 700 + Logitech mx518 comes around or less than 3k, so was thinking of something better in the package for 3k.

Please suggest asap.

Thanks in advance
